A nurse is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Volume (mL) = Desired dose (mg) / Concentration (mg/mL) First, we need to find the concentration: Concentration = 3 g/5 mL = 600 mg/mL Now, we can calculate the volume: Volume = 250 mg / 600 mg/mL = 0.42 Therefore, the nurse should administer 0.4 mL
